Ciência Rural , 2011, DOI: 10.1590/S0103-84782011000800028
Abstract: the aim of this study was to estimate the concentration of milk true protein (tp) by mid-infrared absorbance method (mir) in samples from bulk tank of dairy herds, and to determine the correlation between the results of tp of milk determined by kjeldahl and mir. forty nine dairy herds were selected (17 holstein, 6 jersey and 26 girolando) for monthly collections of samples from bulk tanks during the period of one year (284 samples). fat, lactose, crude protein and total solids were firstly determined by mir, and then analyzed for total and true protein by kjeldahl method. the regression equation to estimate tp contents based on mir crude protein determination was as follows: tp=0.0021+(1.0104xcp), where: tp is the content of true protein, cp is the crude protein content determined by the mir method, and 0.0155 is the model error term.

Pesquisa Agropecuária Brasileira , 2010, DOI: 10.1590/S0100-204X2010001200023
Abstract: the aim of this work was to evaluate the association between milk flow, teat morphological measurements and subclinical mastitis prevalence in gir cows. eighty cows in the 2nd and 3rd lactations, with 90 to 200 days of lactation, were divided according to milk flow during milking into fast or slow groups. teat morphometry was assessed by ultrasound scanning of the right anterior teat and external measurements. milk samples were collected for somatic cells count (scc) and microbiological culture. the effect of milk flow during milking was evaluated by analysis of variance of milk yield, scc, morphometry and external measurements. the association of morphometry and external measurements of the teats with the scc and microorganisms found in milk were analysed. milk flow was significantly correlated to milk production. gir cows with slower milk flow had longer teat canal and greater milk yield, in comparison to cows with fast milk flow. teat-end to floor distance influenced scc of gir cows. prevalence of subclinical mastitis and the type of mastitis-causing pathogens were not affected by milk flow during milking
